Claim.

The present invention relates-to new and useful improvements in sandspreaders, particularly for sanding sidewalks, although it will beunderstood, of course, that the device may be used for any other purposefor which it may be found adapted and desirable.

An important object of the invention is to provide, in a manner ashereinafter set forth, a sand spreader of the aforementioned characterwhich is adapted to be expeditiously mounted for operation on a tractoror other Vehicle.

Another very important object of the invention is to provide a spreaderof the aforementioned character comprising novel means, including theexhaust from the tractor or other vehicle, for uniformly spreading thesand in the desired direction over a considerable area.

Still another very important object of the invention is to provide asand spreader of the character described which embodies unique means forcontrolling or regulating the discharge of the sand.

Another important object of the invention is to provide a sand spreadercomprising means for agitating the sand in a manner to assure a uniformflow or discharge of said sand.

Other objects of the invention are to provide a sand spreader of thecharacter set forth which will be comparatively simple in construction,strong, durable, highly efiicient and reliable in use, compact, light inweight and which may be manufactured at low cost.

All of the foregoing and still furtherobjects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in front elevation of a sand spreader constructed inaccordance with the present invention.

Figure 2 is a view in vertical longitudinal section through the device.

Figure 3 is a fragmentary view in bottom plan.

Figure 4 is a view in horizontal section, taken substantially on theline 46 of Figure 1.

Figure 5 is a detail View in top plan of What may be referred to as thespreader nozzle,

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises ahopper I for the reception of the sand to be spread, which hopper may beof any suitable material and capacity. Also, the hopper I may be securedfor operation on the rearof various types of tractors or othercombustion engine driyen vehicles in any desired'manner.

Depending from the bottom 2 of the hopper I is a discharge spout 3.Fixed on the lower end portion of the discharge spout 3, ondiametrically opposite sides thereof and depending therefrom, is a pairof opposed, parallel metallic guides 4. Mounted for sliding movementtoward and away from each other in the guides 4 is a pair of shutterplates 5 which regulates the discharge of sand from the spout 3. Ears orthe like 6 rise from the outer end portions of the shutter plates 5.Adjusting screws I are threaded through the ears 6 and rotat'ablyconnected at 8 to the spout 3 for adjusting the shutter plates 5. Theelements 4 to I], inclusive, constitute a gate valve for the spout 3.

Mounted beneath the spout 3 for receiving the sand therefrom is a nozzlewhich is designated generally by the reference numeral 9. The nozzle 9is of the shape shown to advantage in Figure 5 of the drawings andcomprises a bottom plate II] from the sides of which apertured ears IIproject. The ears II accommodate rods I2 which depend from the bottom 2of the hopper l for firmly securing the nozzle 9 in position beneath thespout 3. Rising from the plate In is an inclined wall I3 which issubstantially U-shaped in plan. Thus, the front end of the nozzle 9 isleft open for the discharge of the sand. At the front or discharge endof the nozzle 9, the plate I0 terminates in an upwardly inclined flangeI4 constituting a spreading lip which directs the sand upwardly. Theplate I0 further includes a raised portion I5.

Extending downwardly through the'hopper I and the spout 3 into thenozzle 9 is an exhaust gas conduit or pipe It. The lower or dischargeend of the exhaust pipe I6 is located above the raised portion I5 of theplate I0, which raised portion functions as a spreader for the exhaustgases. The pipe I6 may be connected in any suitable manner to theexhaust of the engine of the tractor or other vehicle. The opposed inneredges of the shutter plates 5 are provided with notches or recesses I!which receive the exhaust pipe I6 when said shutter plates are closed.

Operable in the lower portion of the hopper I is an agitator IS. Theagitator I8 is operatively connected to a shaft I 9 by a belt and.pulley connection 20. The shaft I9 may be driven from any suitable ourceof power.

It is thought that the operation of the device will be readily apparentfrom a consideration of the foregoing. Briefly, with the shutter plates5 adjusted as desired, the sand flows by gravity from the hopper Ithrough the discharge spout 3 into the nozzle 9. Exhaust gases underpressure are discharged from the pipe 16 into the central portion of thenozzle 9, said exhaust gases impinging the spreader I5and beingdistributed thereby. The exhaust gases discharge the sand in a blastfrom the nozzle 9, the construction and arrangement being such as touniformly spread said sander/er a considerailelearea in the desireddirection. The agitator l8 prevents clogging and assures a uniform flowof the sand from the hopper l. The shutter blades 5 may be expeditiouslyand accurately adjusted as desired to regulate the volume of sandleaving. the hopper I through the medium of the screws 1. If desired,the spreader may be mounted for operation on the front end of a Vehicle,instead of the rear thereof. Also, the device may be operated,inconjunction with a suitable engine, from a wheelbarrow or other handoperated carrier.

It i believed that the. manyadvantages at a sand spreader constructed inaccordance with the present invention will be readily understood,

and although a preferred embodiment of the de-: vice is as illustratedand described, it is to be understood that changes in the details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is:

A sand spreader comprising a hopper for the the plate in opposedrelation to the discharge end of'the pipe, and an upturned lip on theplate at the outlet of the nozzle for directing the: dischargingsandupwardly.
